    Nice! But is there an app with this algorithm/strategy/design for finding good matches for casually having fun together? All the apps I know suck.

      Why would you need a pairwise matching algorithm for finding friends? Friends are generally not exclusive nor rivalrous

        It's about prioritizing candidates for the costly initial audition, and breaking symmetry for the introduction, something particularly useful for people who can't just approach other at random in a social setting.
